The most accurate and most likely probability is found by having a large, non-biased sample. The answer choice that shows this is D. Determine the ethnicity of 100 men (assumingly selected randomly) from a large city and determine the number who are Caucasian.
This answer choice showcases a large sample group, that was selected randomly from a large city. This would give you varied people to contribute to your study and give you an accurate representation of what the demographics of the city are.
I hope this helps! :)
Yes this seems about correct
Answer:
cant see any of the graphs
Step-by-step explanation:
pls send the graphs
We can find the value of these 2 numbers by setting up 2 equations
x = first number
y = second number
by the what the first sentence in the problem says, we can say that:
6x + 2y = -8
by what the second sentence in the problem says, we can say that:
2x + 8y = 34
now that we have our 2 equations, we can use elimination to get rid of one of the variables. I am going to multiply the second equation by -3, so that we can add the 2 equations together and x will be eliminated.
-3(2x + 8y = 34)
-6x - 24y = -102
now we can add the 2 equations together and solve for y
6x + 2y = -8
-6x -24y = -102
-22y = -110
y= 5
now that we have the value for y, we can plug in 5 for y in either equation and solve for x,
6x + 2y = -8
6x + 2(5) = -8
6x + 10 = -8
6x = -18
x = -3
the two numbers are 5 and -3
hope this helped
